Specific technical data of the DF51-320
The table below contains the specific technical specifications of
the three-phase 230 V series, such as current, voltage, and torque
values.
Primary side: Number of phases Single-phase/three-phase
Primary side: Rated voltage 180 V ~ –0 % to 264 V ~ +0 %, 47 to 63 Hz
Secondary side: Rated voltage
Three-phase 200 to 240 V ~
Corresponding to the primary side rated voltage
If the primary voltage drops, the secondary voltage also drops.

1) If the regenerative braking torque is high, an external braking device with braking
resistor must be used. Alternatively, you can use a DV51 with external braking
resistor and – if required – optional keypad DEX-KEY-6… instead of the DF51. On
the DV51 the braking device function is built in.
